Description
Technical field
The utility model relates to a kind of frozen carrier arrangement of biomaterial efficiently.
Background technology
Vitrifying snap frozen is fused high concentration cryoprotector and embryo/ovum; after certain hour balance; embryo/ovum volume reduces 30-50% because of dehydration; afterwards dehydration embryo/ovum is inserted in freezing year bar; again the freezing year bar being loaded with dehydration embryo/ovum is directly dropped in liquid nitrogen and make dehydration cell instantaneous vitrification; form lower preservation without ice crystal, cause injury to cell to reduce intracellular ice.
Can not be damaged in refrigerating process by freezing year bar of loading dehydration cell in order to protect; and from liquid nitrogen container, easily take out the patient information simultaneously can also telling embryo/ovum; usually sample can be placed in freezing support; and freezing support also needs possess the effect of clamping freezing sleeve pipe; sleeve pipe is put into by freezing year bar; freezing support put into by sleeve pipe; again by the stentplacement in conjunction with freezing sleeve pipe in liquid nitrogen hand basket, liquid nitrogen hand basket is placed in liquid nitrogen container and carries out freezing in-196 degrees Celsius.
The height of each liquid nitrogen container hand basket now used is 40 centimetres (bottom hand basket hollow outs), freezing stent length is 42 centimetres, on freezing support, installation length is the sleeve pipe of 12 centimetres, because freezing stent length is longer, after single sleeve pipe is installed, distance between sleeve opening to freezing support catch is very large, year bar (length is 12 centimetres) being mounted with embryo can be deviate from from sleeve opening, therefore be adopt two sleeve pipes (as shown in Figure 7) of installing positive and negative mutual button on freezing support at present, prevent carrying bar and lose.The storage of current liquid nitrogen container used is highly 40 cm, and be therefore limited to the structure of above-mentioned liquid nitrogen container hand basket and freezing support, existing liquid nitrogen container only can store one deck embryo, and liquid nitrogen container utilization ratio is lower.And liquid nitrogen container is expensive, some liquid nitrogen container even needs unit up to ten thousand, therefore the availability improving liquid nitrogen container can reduce the equipment cost needing unit embryo being carried out to stored frozen.
Summary of the invention
The technical problems to be solved in the utility model is: provide the frozen carrier arrangement of efficient biomaterial that a kind of liquid nitrogen container availability doubles, the use of the frozen carrier arrangement of this biomaterial can make the storage capacity of current liquid nitrogen container used double, and solves above-mentioned prior art Problems existing.
The technical scheme solved the problems of the technologies described above is: a kind of frozen carrier arrangement of biomaterial efficiently, comprise nitrogen tank hand basket, freezing support and the sleeve pipe for placing year bar, described nitrogen tank hand basket is mainly formed by hand basket with the shadoof of hook, described shadoof is flat cuboid, described hand basket is the bucket body structure of upper end open bottom end seal, described hand basket comprises top hand basket and bottom hand basket, bottom hand basket is fixedly connected with shadoof, top hand basket is flexibly connected with shadoof, described top hand basket is provided with location annulus, bottom hand basket is provided with lower location annulus, fastening screw is placed with in upper location annulus and lower location annulus, the height H of described hand basket is 20 ~ 21cm, distance D1 between top hand basket and bottom hand basket is 2 ~ 3cm, described freezing support comprises semi-circular bracket and is arranged on the circular arc lug for fastening sleeve pipe at semi-circular bracket edge, one end of semi-circular bracket is provided with catch, distance D2 between this catch and ferrule openings end is 1 ~ 2cm, the length L1 1 ~ 2cm larger than the height H of hand basket of semi-circular bracket, the length L2 2 ~ 3cm less of the length L1 of semi-circular bracket of sleeve pipe.
Further technical scheme of the present utility model is: described shadoof has through hole, and top hand basket is arranged on shadoof by the bending bar through shadoof through hole.
Another further technical scheme of the present utility model is: described shadoof has through hole, top hand basket is provided with screw rod, and screw rod is passed the through hole of shadoof and fixed by nut.
Described top hand basket is also configured with lid.
Described semi-circular bracket is also provided with information signboard.
The utility model keeps with in the much the same situation of present level at hand basket height, the hand basket of original about 40 centimetres is improved to about two the 20 centimetres of little hand baskets arranged and (bottom each hand basket, does the end with stainless steel aluminium sheet, prevent liquid nitrogen from missing), bottom hand basket and shadoof are fixed, and top hand basket is flexibly connected with shadoof, namely top hand basket can rotate to the angle (as shown in Figure 4) vertical with shadoof, convenient when taking out the embryo in the hand basket of bottom, top hand basket can be rotated down and still be dipped in liquid nitrogen, to ensure the quality stored.Adopt this structure, the storage capacity that current liquid nitrogen pot fetching used can be made to double, avoids making a big purchase liquid nitrogen container in large quantities, reduces the economic input buying liquid nitrogen container, for applying unit has saved cost, also avoids adding the loss that a large amount of liquid nitrogen container causes liquid nitrogen.In addition, a large amount of liquid nitrogen containers needs large-area place to place, and use of the present utility model can save the placement place of liquid nitrogen container.
Below, in conjunction with the accompanying drawings and embodiments the technical characteristic of the frozen carrier arrangement of a kind of efficient biomaterial of the utility model is further described.
